Dihexa vs Ovagen

Side-by-side comparison of key properties, dosing, and research.

Cognitive Enhancement
Dihexa
Anti-Aging & Longevity
Ovagen
Summary
Dihexa is a potent experimental oligopeptide derived from angiotensin IV that dramatically enhances synaptogenesis. Preclinical research shows cognitive enhancement orders of magnitude more potent than BDNF — it is considered one of the most powerful nootropic compounds in research, but has very limited human safety data.
Ovagen is a tripeptide bioregulator (Glu-Asp-Leu) developed by Professor Vladimir Khavinson, primarily targeting liver tissue. It supports hepatocyte function, liver cell regeneration, and protection against hepatic aging and disease. Ovagen is used in protocols for chronic liver disease, hepatoprotection, and metabolic liver conditions including fatty liver disease.

Key Benefits
  • Dramatically increases synapse formation (potentially 10 million× more potent than BDNF in animal models)
  • Enhances memory and learning
  • May reverse cognitive decline
  • Improves neuroplasticity and executive function
  • Long-lasting cognitive benefits from short courses
  • Potential therapeutic agent for Alzheimer's
  • Hepatoprotective effects against toxic, viral, and metabolic liver damage
  • Promotes hepatocyte regeneration and liver tissue repair
  • May reduce liver fibrosis progression
  • Supports liver metabolic function and detoxification capacity
  • Anti-aging effects on hepatic tissue
  • Useful in NAFLD/MASH supportive protocols
  • Compatible with NAD+, glutathione, and BPC-157 in liver health stacks
Side Effects
  • Headache
  • Irritability
  • Brain fog during washout period
  • Unknown long-term effects (insufficient data)
  • Generally well tolerated
  • Mild injection site reactions
  • No clinically significant hepatotoxicity reported
